Mathematical physicists

Gustavo Colonnetti (8 November 1886 – 20 March 1968) was an Italian mathematician and engineer who made important contributions to continuum mechanics and strength of materials. He was a Rector of the Politecnico di Torino and President of CNR (Consiglio Nazionale delle Ricerche). His theories found important applications in modern techniques of construction, such as pre-stressed concrete.He is remembered for Colonnetti's theorem (or Colonnetti's minimum principle) which states that in equilibrium the potential energy function W* is minimized.

Yvonne Choquet-Bruhat (French: [ivɔn ʃɔkɛ bʁy.a] ; born 29 December 1923) is a French mathematician and physicist. She has made seminal contributions to the study of Einstein's general theory of relativity, by showing that the Einstein equations can be put into the form of an initial value problem which is well-posed. In 2015, her breakthrough paper was listed by the journal Classical and Quantum Gravity as one of thirteen 'milestone' results in the study of general relativity, across the hundred years in which it had been studied.She was the first woman to be elected to the French Academy of Sciences and is a Grand Officier of the Légion d'honneur.
